title: Mechanism of the rel defect in beta-galactosidase synthesis.
abstract: Relaxed (relA) mutants of Escherichia coli are defective in beta-galactosidase synthesis during amino acid limitation. We show here that this defect comprises both a transcriptional component and a translational component.
